MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Jan. 2, 1912.

Application filed September 16, 1909. Serial No. 517,977.

To all whom t may concern:

Be it known that I, BERNARD C. ELLER- SICK, a citizen of the UnitedStates, and resident of St. Louis, Missouri, have` invented certain newand useful Improvements in Music-Leaf Turners, of which the following isa specification containing a full, clear, and eXact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in music leaf turners, the objectof my invention being to construct a music leaf turner which may beadjusted to receive sheets of music of various lengths and widths and toprovide therefor a number of spring act-uated clip-carrying arms withmeans for releasing one arm at a time to permit the arm to be swung bythe spring from one side of theframe to the opposite side and carryingwith it a sheet of music in the clip.

For the above purposes my invention consists in certain novel featuresof construction and arrangement of parts as will be hereinafter morefully described, pointed out in my claim and illustrated in theaccompanying drawings: in which:

Figure 1 is an elevation of the complete music leaf turner with a sheetof music therein, a portion of which is broken away to illustrate thelowermost clip for holding music to t-he frame of the device; Fig. 2 isa plan of the complete music leaf turner; Fig. 3 is a vertical sectionalelevation taken on the line 3-3 of Fig. 1, the sheets of music beingremoved therefrom; Fig. 4 is an enlarged detail sectional elevationshowing the arrangementof the supporting ends of the arms for turningthe sheets of music; Fig. 5 is a sectional plan taken on the line 5-5 ofFig. 4; Fig. 6 is an end view of a portion of the frame showing themeans for supporting the leaf-turning arms at their outer ends afterhaving turned the music sheet; Fig. 7 is an inside face view of thetripping device which permits the release of one arm only at a time;and, Fig. 8 is a vertical sectional elevation taken on the line 8-8 ofFig. 7

Referring by numerals to the accompanying drawings: 1 designates thebase of the device to the under face of which is applied a pad 2.

3 designates the upper portion of the frame of the device to the rearface of which is applied a pad 4.

Connecting the frame section 3 with the base 1 are the uprights 5, theouter two of which are bent at right angles at their lowermost ends,which bent ends are secured to the upper face of the base 1, and theopposite ends of the outer uprights are secured agalnst the forward faceof the frame section 3.

The middle upright 5 is provided with a right angle bend 6 at each ofits ends, the bend at the lower end being secured to the base in thesame manner as the two outer uprights and the opposite end of the middleupright is secured to the face of the frame sect-ion 3, its bent endoccupying a position above the frame section 3 andV projecting forwardlyfrom the section 3.

Secured between the bent ends 6 of the middle upright is a rod 7 andcarried by said rod is a pair of clips 8, and carried by the lowermostclip 8 is a bolt 9 carrying a winged nut 10.

Formed in the middle upright 5 is a slot 11 through which the bolt 9 ispassed to provide altitudinal adjustment of the lowermost clip S asrequired for the accommodation of music leaves of various lengths.

Embracing the rod 7 adjacent its upper end is a plurality of collars 12each of which is provided with a reduced portion 13, which reducedportion is embraced by a helical spring 14 the one end of which issecured within the depression 13 and its opposite end is secured to aperforated cleat- 15,` secured to the forward face of the middle upright5.

To secure the collars 12 against altitudinal movement is a collar 16which embraces the rod 7 immediately below the lowermost collar 12 andis secured to the rod 7 by means of a set screw or the like 17.

Each of the collars 12 carries `an arm 18,

the arm on the uppermost collar being straight and the inner ends ofeach of the remaining arms are bent outwardly thence upwardly so thatall of the arms occupy approximately the same horizontal plane.

Carried by the arm 18 is a spring clip 19 and to provide means foradjusting the clip 19 longitudinally of the arm 18 is a hanger 20 whichis bifurcated at its upper end to straddle the arm 18 and a set screw 21is extended through said bifurcated end.

The right hand end 22 of the frame section 3 is bent forwardly at rightangles to its body portion and secured to the outer end of the bentportion 22 is a guide 23, and extending the full length of the bent end22 on the inside face thereofis a channel bar 24 arranged to receive andsupport the free ends of the arms 18.

A bracket 25 is lixed to the forward face of the frame section 3adjacent its right hand end and pivoted thereto is a spring actuatedhook 26. Formed integral with the hook, adjacent its free end, is anoutwardly and laterally extending projection 27.

Supported in the guide 23 is a rod 28, preferably angular in crosssection, to prevent its turning. The upper end of the rod is threaded toreceive a nut 29, which nut is arranged to secure to the rod a washer 30and anr eXtensible coil vspring 31 impinging between the washer 30 andthe guide 23.

Carried by the rod 28 is a pin 32 which normally occupies a position ina plane above the projection 27 of the hook 26. Carried by the rod 28 isa dog 33, a portion of which parallels the rod 28 and the free end ofwhich normally occupies a position in a plane above the arms 18.

Pivoted to the right hand upright 5 is a lever 34 and connecting thelever' and the lowermost end of the rod 28 is a rod 35.

Adjacent the upper left hand corner of the frame is an arm 36, the freeend of which is bent downwardly to receive and support the arms 18 whenreleased from the opposite or right hand side of the device.

In the operation of my improved music leaf turner, assuming that thedevice is in position on a piano or the like and a piece of music issecured in the clips 8 and that each of the individual leaves of thepiece of music is held at its upper margin by one of the clips 19 andthat all of the arms 18 are swung to the right hand end of the device,their ends occupying a position in the channel bar 24 and the hook 26holding them against movement and against pressure of the springs 14,when it is desired to turn a leaf of the music, the lever 34 isdepressed and by reason of the connection between the lever 34 and therod 28, the pin 32 engages with the projection 27 and the hook islowered permitting one of the arms to be swung outwardly away from thehook and be carried by its spring 14 to the opposite end of the device,and be received and supported by the arm 36 Simultaneously with therelease of one of the armsv 18, the dog 33 is moved downwardly inadvance of the next succeeding arm and retains it during the time thehook 26 is lowered. By the time the dog 33 is raised by the pressure ofthe spring 31 to a position releasing the arm 18 the hook 26 is in aposition to receive and retain said arm 18. In this manner eachoperation of the lever 34 lowers the hook 26 to permit the movement ofan arm 18 and at the same time and by the same movement of the lever 34the dog is brought to a position to prevent the movement of more thanone arm 18 at a time.

I claim:

In a music leaf turner, the combination with a frame, a plurality ofarms, which are spring actuated for movement in one direction, ofdevices at each end of the frame for supporting said arms, a springactuated, pivoted hook arranged adjacent the right hand frame supportingdevice, a rod being spring actuated in one direction, a pair ofprojections carried by the rod, one projection being constructed andarranged to move said hook to release one of said arms at a time and theother projection constructed to pass in front of the remaining arms toprevent their turning, substantially as shown and for the purposesstated.

In testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.

BERNARD C. ELLERSICK.
